Hardwired for the trail, the Men's Zeta AR Jacket is built for exploring big terrain. Protection comes from Gore-Tex fabric with C-Knit backer technology. This material delivers durable waterproof, windproof, highly breathable performance with a backer technology that makes the fabric exceptionally supple, quiet and comfortable. Arc'teryx' Trim fit keeps the shell close to the body to improve the fabric breathability, but leaves room for light layers. Articulation in the sleeves and gusseted underarms provide freedom of movement.Extended trips require smart features, fit and protection. The Zeta's water-resistant pit zips provide rapid ventilation. The low profile Arc'teryx StormHood delivers full protection and cinches securely with a single adjuster for a fit that moves with the head and provides exceptional peripheral vision. The hip length with drop back hem extends coverage and rides comfortably under a hipbelt. An internal laminated pocket stows and protects a smartphone or wallet, and two hand pockets with water-resistant zips are accessible while wearing a pack or harness.
